I think it's something you could express in 'radians per timestep' where
by radians I mean the amount the wheel body rotates on the axle axis.  
The larger that gets, the more unpredictable the wheels get.  I doubt the
hinge motor speed matters, except in that it's coincidentally probably
pretty close to the true rotation speed.

I haven't tried that, but based on what little I know about the
problem, I'm pretty sure that would help.
